Influence of Intraoperative Medial Collateral Ligament Bony Avulsion Injury on the Outcome of Primary Total Knee Arthroplasty

BackgroundThe purpose of this study is (1) to find the clinical and radiological outcome of intraoperative bony avulsion of medial collateral ligament (MCL) treated with screw and washer construct and (2) to predict the preoperative factors which may contribute to the avulsion-type MCL injury during primary total knee arthroplasty (TKA).MethodsIntraoperative MCL avulsion injury occurred in 46 (0.8%) of the 4916 consecutive primary TKA from January 2011 to December 2015. After exclusion, the 41 knees were matched 1:2 with controls without MCL injury and compared for the various clinical, radiological, and functional parameters. The clinical parameters analyzed were age, gender, body mass index, preoperative diagnosis like osteoarthritis or rheumatoid arthritis, range of motion, sagittal deformity, and vitamin D levels. The radiological parameters calculated were coronal deformity, proximal tibial varus angle, distal femur valgus angle, joint line congruence angle, posterior tibial slope, “cup and saucer” morphology, presence or absence of knee subluxation, tibia vara, and femoral bowing. The preoperative and postoperative Knee Society Score and Knee Society Functional Score were analyzed. Complications or revisions, if any, were noted during the follow-up. Multivariate logistic regression analysis was used to predict the preoperative risk factors for MCL avulsion injury.ResultsAt a mean follow-up of 58.4 ± 19.3 months, there were no radiological or physical examination findings of instability. Compared to the preoperative disability, there was a statistically significant improvement in clinical scores (Knee Society Score and Knee Society Functional Score) in the final follow-up (P < .001) in both cases and the control group. The mean preoperative coronal deformity was 170.6 ± 6.96 in the study group and 167.7 ± 4.3 in the control group (P = .021). The mean preoperative tibial slope was 10.5 ± 4.9 in the study group and 7.91 ± 4.15 in the control group (P = .003). The preoperative knee subluxation was present in 48.8% knees (P < .001) and “cup and saucer” morphology in 68.3 knees (P < .001) in the study group. The adjusted odds of MCL avulsion injury were greater for severe varus deformity (odds ratio [OR] 1.462, 95% confidence interval [CI] 1.15-1.86), knee subluxation (OR 39.78, 95% CI 3.78-418.86), and “cup and saucer” morphology (OR 33.11, 95% CI 5.69-192.66).ConclusionIntraoperative MCL bony avulsion injury can be managed successfully with screw and washer construct without the need for increased prosthetic constraint in primary TKA. The presence of severe varus deformity, knee subluxation, and “cup and saucer” morphology tend to have an increased chance of MCL avulsion injury.     

制动对兔膝内侧副韧带的影响

目的:探讨12周制动对兔内侧副韧带生物力学与形态学的影响。方法:选用15只兔,10只行右后肢膝关节全屈曲位内固定12周。取内侧副韧带进行生物力学测试和形态学观察。结果:MCL横截面积缩小,最大负荷、能量吸收明显减少,与对侧和正常比较有显著性差异(P<001或P<005),最大应力、弹性模量、材料常数等材料特性指标也存在显著性差异。应力—应变曲线与对侧和正常组呈分离状态。胶原纤维排列紊乱,韧带胫骨止点出现溶骨性吸收,断裂方式全为止点处撕脱。结论:制动不仅改变韧带骨组合体的结构特性,也影响韧带物质的材料特性。     

Endoscopic Total One-Piece Medial Meniscectomy: Its Effect on the Medial Collateral Ligament

Meniscus specimens from 10 patients subjected to endoscopic total medial meniscectomy were examined for remnants of the collateral ligament. Very small amounts were found in the postero-medial area of the specimens. None exceeded 2 mm in length or breadth and could be found in only one of the sections. With our technique for endoscopic total meniscectomy the integrity of the medial collateral ligament is not violated and ligamentous instability can be avoided.

异体肌腱两种方式重建膝内侧副韧带陈旧损伤

目的探讨异体肌腱解剖重建治疗膝内侧副韧带陈旧性损伤的临床效果。方法 2007年3月至2012年2月,收治64例膝内侧副韧带陈旧性损伤患者。男44例,女20例;年龄20~46岁,平均36岁。所有病例外翻试验在膝关节伸直0°及屈膝30°位均呈阳性。双膝伸直位外翻应力位X线片示:双膝内侧关节间隙差3~5 mm 8例,5~10mm 52例,大于10 mm 4例。MRI示内侧副韧带均有损伤的影像学表现,T2相上可见高信号。受伤至入院时间为3~12个月,平均5.8个月。将患者按损伤程度平均分为两组,其中甲组32例患者采用异体半腱肌腱仅重建内侧副韧带浅层前纵束结构,乙组32例患者采用异体半腱肌腱解剖重建浅层及后斜韧带,均采用可吸收挤压螺钉固定。结果术后切口除1例外均Ⅰ期愈合,64例均获随防,随访时间12~58个月,平均30个月。末次随访时根据改良LysholmScale评分标准,甲组优16例,良10例,可6例,优良率为81.25%,乙组优20例,良11例,可1例,优良率为96.88%,均较术前明显改善,两组比较乙组优于甲组,差异有统计学意义。结论使用异体肌腱解剖膝关节内侧副韧带陈旧损伤,重建全面可靠,易于操作,较单纯重建浅层结构临床效果良好。     

Modified Medial Collateral Ligament Indentation Technique in Total Knee Arthroplasty with Severe Type II Valgus Deformity

ObjectiveTo explore the feasibility and clinical efficacy of a modified medial collateral ligament indentation technique in total knee arthroplasty (TKA) with severe type II valgus deformity.MethodsConsecutive patients with Krackow type II valgus deformity >20° who underwent a primary unilateral TKA between May 2008 and June 2017 were studied retrospectively. A medial collateral ligament indentation technique was performed in 20 patients (MCLI group), and 23 patients received the routine lateral structures release technique (LSR group). Radiological parameters, such as the valgus angle (VA), and functional outcomes including the use of constraint implants, Knee Society Score (KSS), Knee Society Function score (KSF), and thickness of the polyethylene insert were compared between the two groups.ResultsA total of 43 consecutive patients had a minimum 2‐year follow‐up. The preoperative VA was comparable between the MCLI (23.5° ± 5.8°) and LSR groups (21.3° ± 3.2°, P = 0.134), as was the postoperative VA (1.1° ± 2.1° and 2.5° ± 3.0°, respectively, P = 0.084). The mean KSS and KSF scores in the MCLI group were 30.2 ± 4.8 and 38.8 ± 4.8, respectively, before surgery, and they increased to 91.3 ± 2.6 and 86.5 ± 2.4 at the last follow‐up. The scores in the LSR group were 31.5 ± 7.5 and 36.5 ± 7.8 before surgery and 92.4 ± 3.5 and 88.5 ± 3.6 at the last follow‐up. While no statistically significant differences in pre‐ or postoperative functional scores were found between the two groups, the MCLI group had thinner polyethylene inserts (9.5 ± 1.1 mm vs 12.9 ± 1.5 mm) and less use of constrained condylar inserts (15% vs 69.6%). During follow‐up, the MCLI group had fewer complications.ConclusionA modified MCLI technique can achieve good outcomes in TKA with type II valgus deformity of >20°. It can maintain a normal joint line level, reduce the use of constrained condylar knee prostheses, and is a reliable choice for severe genu valgum.
